WILLIAM E. SPARKS, OF NEW BRITAIN, CONNECTICUT, ASSIGNOR TO P. 81; F.CORBIN, OF SAMEPLACE.

SLIDING-DOOR LOCK-HANDLE.

SPECIFICATION forming part of Letters Patent No. 226,682, dated April20, 1880.

Application filed March 13, 1880.

To all whom it may concern:

Be it known that 1, WM. E. SPARKS, of New Britain, in the county ofHartford and State of Connecticut, have invented certain new and usefulImprovements in Flush Handles for Sliding Doors, of which the followingis a specification.

My invention relates to improvements in flush handles in which a slidingpull, weighted lever, and push-pin are connected together, so that thepull is drawn into the case by gravity and thrown out by the push-pin;and the object of my invention is to make a cheap and easy workingdevice.

I attain this object by the mechanism illustrated in the accompanyingdrawings, in which- Figure l is a front elevation. Fig. 2 is a sideelevation with one of the case-plates removed. Fig. 3 is a like view,represented with the handle or pull partially extended.

I arrange this pull in the same case with a lock of any ordinaryconstruction, and which forms no part of my invention.

A represents the pull or handle, the outer end of which slides through amortise in the face-plate D, and the opposite end of which is governedby a fixed stud, a, on the lock-case, the shank of the pull beingslotted so as to embrace said stud.

Upon the shank ofthe pull A is a pin or stud, b. Below this pull is aweighted angle-V lever, B, the same being pivoted to the lockcase uponthe post 0, which constitutes the fulcrum of said lever. Thearm d ofthis lever is a weighted arm, while its arm 6 is slotted to receive thepin 11 of the pull A. This arm is thinner than the arm d, so that itrides by the side of the shank of the pull A.

A push-pin, C, is arranged with one of its ends projecting through amortise or hole in the face-plate l), and with its other end slotted andengaged with, so as to be governed by, the base of the pivot c-that is,the pivot 0 extends through the inner slotted end of the push-pin C.

A lug or projection, h, upon the push-pin C comes in front of theweighted lever B a little below the pivot c.

The mortise or opening in the face-plate D through. which the end of thepush-pin C passes is countersunk or beveled on its front (ModeL) side,so that the end of the push-pin may be set with its end flush with thegeneral surface of the face-plate D, and yet allow it to be depressedsomewhat by means of a finger or thumb applied to its outer end.

When the parts are at rest the weighted arm (1 of the lever B issufficiently heavy to hold the parts in the position represented in Fig.2, and with the pull A drawn inward, so that its outer end is flush withthe face-plate D. When in this position the door may be slid into thepartition or other surrounding frame, so that nothing but its edge isexposed to view.

When it is desired to withdraw the door from this position for thepurpose of closing it, it is only necessary to depress the end of thepush-pin C, when the projection h on said pin will strike the lever B,elevate its weighted arm (I, and throw its slotted arm 0, together withthe pull A, outward, and bring said parts into the position representedin Fig. 2. The pull is then extended far enough to be convenientlygrasped for closing the door, and upon pulling it to do so it will firstmove outward a little until its inner slotted end engages the stud a onthe case, after which pulling upon the handle will draw the door withit. Upon releasing the pull A the weight of the arm (I of the lever B issufficient to return the parts to their normal position.

By this mechanism the parts work very smoothly and nicely, and only aslight motion of the push-pin is necessary in order to project thehandle or pull sufficiently for graspmg.

I am aware that tlush handles for sliding doors containing the pull anda stop-pin are old when the two were connected by springs and mechanismwholly different from that herein shown.

I claim as my invention The combination of the sliding pull A, bearingpin I), the weighted angle-lever B, having the slotted arm 6 andweighted arm d, and the push-pin C, having the projection h, allcombined and operating substantially as described, and for the purposespecified.

WILLIAM E. SPARKS.
